Emily, you couldn´t have foreseen this and you did everything to make him comfortable in the heat. Sometimes, these things just happen, I´ll now be extra vigilant with mine although when they´re outside now, their area is always shaded.
I will miss little Pip, I keep looking at that photo and can´t quite believe it so I can´t imagine how you´re feeling. I´ve been back having a look at your lovely bunny family, hope they are all well and I bet they´ll also miss Pip. They´ll make you feel better, I´m sure, it´s funny how animals always know how we´re feeling. Stay strong and we´ll be here if you need us.
